If you are on the Twitter Beta for Android, this is nothing new for you. However, if you are not - as most of us - this is a new feature which is hitting your Android and iOS smartphone and tablet today. As Twitter just announced, it's releasing updated Twitter apps for the above mentioned mobile OS to make it easier for everyone to experience those photo and video moments on Twitter. Starting today, timelines on Twitter will be more visual and more engaging by featuring a previews of Twitter photos and videos from Vine, which will be front and center in Tweets. To see more of the photo or play the video, just tap. Furthermore, Twitter said it also made it easier to reply, retweet or favorite a Tweet without leaving the timeline - by just tapping right inside the tweets in the timeline.

As said, the update will be available for Android and iPhone (but as "always" not for Windows Phone) and Twitter said it's even making the new photo and video previews available on Twitter.com.
